Which is why, the definite link has been mentioned on the first post on where to specifically download the alpha release.

It's great that now we have a new version available but it is disappointing that it is not stable yet. Oh well, we don't live in a perfect world and will be waiting for all the errors to be fixed soon.

Fellows, PLEASE get reasonable, do you really expect somebody to know,
when a stable Version of something will be ready ? Not even Microsoft would
know such, otherways, there would be no MS-Updates for existing Windows
Versions needed ever !

And OC has not 100's of Testers employed, it's YOUR DUTY, as PART of those
OC Testers, to find out, where and what is still missing, or does not work. That's
the main Reason, why OC comes for FREE, otherways, why should anyone build
such a comprehensive Software for free? Just to make you happy ?!
Got it ?
What a bunch of dreamers...

As long as they are thoroughly testing this release, I think it is good that the stable version is not released yet. I have seen plenty of posts where people were not happy about releases coming without enough testing.
